CVE-2026-75144

A flaw was found in FFmpeg. Attackers can trigger memory corruption in the VC-2/Dirac RTP packetizer by supplying a specially crafted Dirac data unit. This heap buffer overflow occurs because the packetizer copies input data into a fixed-size buffer without proper size validation. This can lead t...

CVE-2026-75147

A flaw was found in FFmpeg's AV1 Real-time Transport Protocol RTP packetizer. A local attacker could entice a user to process a crafted AV1 input packet. This crafted packet could cause an out-of-bounds read, potentially leading to information disclosure or a denial of service DoS condition...
